Growth spurts or “frequency days” are times when your baby seems to want to breastfeed all the time. Growth spurts are common around 3 weeks, 6 weeks, 3 months, and 6 months of age, but growth spurts can happen at any age. A growth spurt usually lasts about 2–3 days but can last a week or more.
Because your baby may seem cranky, fussy, or out of sorts, well-meaning but inexperienced friends and relatives may suggest that “your milk isn’t rich enough,” that “you’re not making enough milk,” that “a formula supplement or solid foods are necessary,” or that “it is time to stop breastfeeding.”
In fact, just the opposite is true. It is time to breastfeed more, albeit temporarily. Your body naturally regulates the amount of milk it produces in response to your baby’s needs. The more milk your baby takes from your breasts, the more milk you make. There is no reason to worry that you can’t or won’t make enough breast milk to satisfy your growing baby. Your body will respond to your baby’s frequency days by making more milk.
Be patient during growth spurts. Resist the temptation to offer supplements. Once your body gets the message, it will ramp up its supply to meet your baby’s needs.
